Hi there, I have a problem which I would like to use perl to resolve, however I'm not sure if it is possible to do.
I need to scan a file and check some conditions, first if field 9 is duplicated on 1 or more rows, then I need to check field 10 to see which is the greater value and then only print the whole row where field 10 is the greater, if field 9 is not a duplicate then print the whole row. An example of the data is below. 28525|U2|4CY0|50|6775.15|2002-02-07|10461|321.43|102040724|102040773| 28526|U2|4CY0|25|3571.78|2002-02-07|6107|167.74|102040774|102040798| 28527|U2|4CY0|50|6930.3|2002-02-07|11376|324.12|102040774|102040823| 28528|U2|4CY0|25|4640.28|2002-02-07|4800|217.43|102040824|102040848| 28529|U2|4CY0|50|8432.05|2002-02-07|9023|392.03|102040824|102040873| Dave
